I used the Aussie Map on the weekend with the Q4 slip on. Worked beautifully. Wondering what you mean exactly by "shoots the mapping all to hell"? Thats good news. I will try the Aussie maps myself if they are working good on your bike... What I meant by "installing the FMF shoots the mapping all to hell" is because I tried the maps on the GYTR programming sheet that are intended for the stock exhaust system, and they don't run well at all on my bike with the FMF... so that basically left me with just the one single FMF map until some new ones started to surface.
